Abstract (en)
[origin: EP0767016A2] The method involves using components (10) having two cylindrical surfaces. An inner surface (14) faces a centre of curvature, a second surface (12) faces away from it. The length of the radius (Ri) of the inner surface is calculated as a ratio, from the radial distance (b) of both cylindrical surface forming the dividend and a divisor. The divisor is the difference of the quotient of the curvature length (La) of the outer surface, divided by the length (Li) of the inner surface, minus 1. The radial distance (b) between the cylinder surfaces is measured after measuring of the curvature length, at least one of which is measured contact-free.
